Application filed August 9, 1911. Serial N0. 643,193.

To all whom t may concern 1de it known that I, JAY W. VAUGHAN, a citizen of the United States of America, re-

siding at Detroit, in the county of Wayne and State ofk Michigan, have inventedcertain new and useful Improvements in Molds for Cement Beams, of which the 'following is aspecilication, reference being hadtherein to the accompanying drawings'.

'In forming beams ofconcrete or other cementitious material it is necessary, in order that the work be done economically, that thel mea-ns by which the -beams are molded beso arranged as to be available for making beams of different lengths. It is also necessary, in order to make the beams proitable, that the molds or system of molds bywhich theyare formed be arranged'so that the molds can be taken away from the beams before the latter are fully set, for usein forming other beams, and that the beams when uncovered by the molds-be left in such a position as to dry out readily and be rapidly hardened so as to be ready for use without undue loss of time.

rlhis invention relates to a mold system for forming beams for building purposes of cementitious material which are so arranged that the parts can be used for making beams of different lengths, and are so arranged that the parts of the system can be withdrawn before the beams are thoroughly set and be used iii-making other beams, the unl covered beams being arranged so as to dry thoroughly ready for use without further attention or the need ofl rehandling themy during the drying out'process.v

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure 1' is a view in perspective of a portion of a mold'system that embodies-features of the invention ,Fig 2 is a view in horizontal section through a portion of the mold system; Fig. 3 is a view partially in end elevation and partially in section showing the disposition of beams after they have been molded by the system and have been left in position for the drying out process; Aand yFig. l is a view in detail of the end portion of one form of beam which may be readily molded by this system.

As herein shown in preferred form, a se? ries of bearing members or stringere l made of wood as herein indicated, or of metal of any preferred mill shape, are each provided y' at one end with a stop 2. A side strip 3cr clamp rests across the bearing members 1 against thestops 2 and has an upright brace 4 or the like, adapted'to support a side` mem- `ber 5 that rests on edge on the bearing members-1 against the clampp. Pallets are disposed in'p'arallel spaced relation across the bearing members or strmgers ll, the

outer pallet abutting the sidemember 5 andk the `others acting as'supportsto hold intermediate walls .or division members 7 in upright position. Suitable bearingplates 8 with gudgeons orfpins 9 thereon are pro` videdv ateach end Iof `the ypallets for attaching crane chain hooks or the like forma- ,nipul'ating the apparatus. -The pallets, side walls `and division members may be either p' of metal or of wood as desired.

`Longitudinallvextensible facings are mounted on the side walls and division members to form faces that give the properform to the sides of beams molded between them. The; system that is hereinv illustrated, is

shown z as- 4designed for makingy I-beams whosefupperand lower flanges have oppositely beveled margins. Accordingly the facings each consist of a stationary member 10,` of sheet :metal or the 'like secured to the side ofa division member or companion side wall between an'upper flange 11 and lower flange 12'adapted to give the `desired dress to the `margin of the produced beam. These lianges extend the entire length of the division members and side `walls and form guides yon which'a second sectionl is lon-v gitudmally movable 1n telescopic engage-` By moving the sections 13 of the facings in or out and Correspondingly4 securing the end walls in position, the pallets, division members and side walls are available for withdrawal ofthe side Walls and division members. A second-v tier of .stringere as indicated in Fig. 3,- are then laid on the partially hardened beams which are suiiiciently set to support the stringere, although not capable at this stage of being' subjected to otherfhandlingt.y A second set of pallets, the withdrawn division members, side walls, and clamps withthe end boards are then placed thereon in staggered relation to" the lower set of beams andalsecondset of beams molded. This processie repeated and as a yresult, a staclrof beams is formed` which are so disposed that the airpasses freelyv around them and allows them to thoroughly season or dry out..v The ydivision members, side walls, clamps and end boards which constitute the most expensive portion of the molds are available for use, the stringere and pallets only being left in position until thebeams are thoroughly set. I.

By this mold system'beams are produced 1 rapidly and economically and are so arranged y as to require minimum floor space for storl age during the drying out process.: Itfis to 2 be understood that the system is notv restricted for use in making beamsof: the particular form herein indicated, but is avail'- I able for molding columns or any parts of a building structure ofanydesired cross section and length. a

Obviously, changes in the details of coni struction may be made 'without-departing from the spirit lof the invention and I do not lcare to limit myself to any particular form crarrangement of parts.

What I claim is l. Af mold system for bems comprising; i

f Witnesses f bearing members, pallets disposed trans versely thereon, division members forming with the pallets a series of adjacent mold pockets, a facing member on the inner face of each division member comprising two eX- tensible sections whereby the length of a facing dress may be varied and end walls adjustably securable between the division members to correspond to the adjusted length of the facing members.

2. A mold system for beams comprising stringere, stops at one end thereof, a clamp bearing against the stops, a side wall secured in upright position against the clamps or the stri-ngers, pallets transversely disposed across the stringers one of which is contiguousrto theside Wall, division memberseach attached on the stringere between and by the pallets, yextensible facing members `on the proximatesides of the division member-sand sidel walls each having a section secured .tothe side wall and a` section longitudinally shiftable on the side wall in telescopic engagement with the fixed' section and end walis resting on' the pallets between the :division members and side walls longitudinally shiftable of the side walls in accordance with the adjusted length of the mold fac-ings. v

3i Iny a mold system for beams, a pallet, division members removably secured against the lateralfmargins thereof, a facing section on the inner face Vof eachdivision member comprising a hollow 'plate having guide flanges longitudinally thereof against the side wall, and a movable section telescoping with the Xed section and moving in the guide flanges thereof, the exterior cross sectional contour of'fthe facing sections proL 'vidinrg the required facing dress to a-molded beam, and end boards spanning the interval between the division members and longitudinally adjustablebn the pallet whereby they maybe'moved into required relation tothe adjusted facing plates.

In testimony whereof I affix my signature in presence of two witnesses.
